How to Increase GABA Naturally: Its Sleep Benefits, Signs of Deficiency, & More

GABA—or gamma-aminobutyric acid—is the main inhibitory neurotransmitter in the brain, meaning that it prevents your nerve cells from firing an action potential (i.e. the body’s form of an electrical signal) (1). This makes it an exceptional amino acid for reducing stress and enhancing sleep.

 

Essentially, neurotransmitters are the chemical messengers of the body—carrying messages between nerve cells (neurons) and other cells in your body. There are excitatory neurotransmitters (like epinephrine and dopamine), inhibitory neurotransmitters (like GABA and melatonin), and modulatory neurotransmitters (like serotonin and dopamine).

List and properties of different neurotransmitters in the human body, including GABA.

These messengers are largely responsible for everything from mood to learning to automatic responses like breathing and heart rate. Without them, your brain and body wouldn’t know how to function.

 

Since GABA is an inhibitory neurotransmitter, it makes for an effective nighttime sleep aid. The higher levels of GABA you have, the more relaxed you will feel—as opposed to being in that stressed-out fight or flight mode that happens when excitatory neurotransmitters are activated.

 

In this article, you’ll learn the benefits of GABA, the signs of deficiency, the recommended GABA dosage for sleep, and the best GABA supplement for sleep.

The Benefits of GABA

GABA, being the body’s primary inhibitory messenger, is found in several brain regions including the hippocampus, thalamus, basal ganglia, hypothalamus, and brain stem (1).

 

Its most renowned benefits include (2):

  • Reduced stress and anxiety
  • The regulation of one’s circadian rhythm
  • An increase in total sleep time
  • A decrease in the time it takes to fall asleep
  • Enhanced memory
  • Improved mood
  • Regulation of motor control (like the coordination and movement of muscles, bones, and nerves)

One 2015 study gave 39 participants either GABA-enriched rice or a placebo for 10 weeks. Results showed that those eating the GABA rice saw an improvement in mental status and sleep quality, while overall stress gradually reduced (3).

 

In another study conducted in 2019, 30 participants were given either oolong GABA tea (containing 2.01 milligrams of GABA) or regular oolong tea (containing 0.25 milligrams of GABA). Their heart rate and stress were analyzed…

 

Both groups of tea drinkers experienced lower levels of stress; however, those drinking the GABA tea saw more relaxation, improved parasympathetic functioning, and a significant decrease in stress (4).

Signs of a GABA Deficiency

Although GABA deficiencies are fairly uncommon, it’s important to know what to look out for.

 

Low levels of GABA have been linked to the following (1):

  • Acute and chronic stress
  • Feelings of anxiety
  • Sleep disturbances like insomnia
  • Psychiatric conditions like schizophrenia
  • Depression
  • Autism
  • Seizures and epilepsy
  • Inattention
  • Hyperactivity
  • Obsessive-compulsive disorder (OCD)
  • Chronic pain

GABA Dosage for Sleep

Without enough GABA, one may experience heightened stress and anxiety, poor sleep, and more. Too much GABA, on the other hand, can lead to oversleeping, daytime sleepiness, and slow, ineffective breathing (5, 6).

 

Although there isn’t a set dosage for GABA at the moment, studies have been carried out that measure the sleep benefits of those taking between 100 and 300 milligrams (mg) of GABA for 1 to 4 weeks. Future research is needed in order to determine the minimum and optimum GABA dose needed to enhance sleep (2).

GABA’s Sleep-Enhancing Side Kick

Melatonin—also known as the sleep hormone—is another natural sleep aid that also happens to enhance GABA’s inhibitory effects (7). And because both melatonin and GABA are known to regulate sleep, they’re a dream team when it comes to getting deep, quality sleep.

 

Add in L-theanine, magnesium, and collagen, and you have a sleepytime tea that will have you feeling relaxed and ready for bed in as little as 30 minutes.

 

Uniquely crafted for those who toss and turn, have trouble falling asleep, or who just can’t seem to turn their brain off at night, Collagen PM provides deeper, longer, and more restorative sleep all night, every night.

The Bottom Line

Rather than turning to Benadryl or Xanax to fall asleep, incorporate a natural sleep aid like GABA into your bedtime routine. As an inhibitory neurotransmitter, it has the ability to prevent your nerve cells from firing—helping you to “turn off” your brain so that you can get peaceful, uninterrupted sleep.

 

In addition to this, GABA helps regulate your circadian rhythm, while significantly increasing rapid-eye-movement (REM) sleep time—the stage of night when you’re likely to have vivid dreams (8).


By drinking a sleepytime tea (with just hot water and one scoop of Chocolate, Honey Chamomile, or Lemon Collagen PM), you’ll be able to get your nightly dose of GABA—along with melatonin, magnesium, L-theanine, and collagen—helping you to fall asleep in as little as 30 minutes.
